摘　　要：奥斯特瓦尔德熟化现象是一种经典物理化学过程,认识并控制奥斯特瓦尔德熟化过程一直是材料领域的重要科学问题。本实验旨在通过使用扫描隧道显微镜(scanning tunneling microscope,STM)引导学生从分子水平直接观察奥斯特瓦尔德熟化现象的微观过程,将物理化学中的抽象概念具象化,加深学生对基本物理化学现象的理解,培养学生“发现问题—分析问题—解决问题”的科学思维模式,激发他们对于科学前沿问题的探究热情,为培养高素质科研后备力量打下一定基础。The Ostwald ripening phenomenon is a classical physical chemistry process,and understanding and controlling it has always been a significant scientific challenge in the field of materials.This experiment is designed to guide students in directly observing the microscopic processes of Ostwald ripening at the molecular level using a scanning tunneling microscope(STM).It aims to concretize abstract concepts in physical chemistry,deepen the understanding of fundamental physical phenomena,cultivate a scientific mindset of 'identifying problems,analyzing problems,and solving problems',ignite their passion for exploring cutting-edge scientific questions,and lay a foundation for nurturing highly capable research talents.
